This is almost exactly the same question I asked here in the Lounge about 7 years ago. I was struggling with something and it wasn't working as I expected it to and hence the frustration.
@JeremyFalcon gave a really good response to that question and 7 years later I fully agree with him.
Most of the hate JS gets is from people who are new to it, and probably have an expectation of how it would/should work. When it does not (and not always due to a straight forward reason) it gets frustrating.
Historically JS has been riddled with issues. It still is. But over the years most of the major issues with JS are now avoidable when we use it a certain way.
For example, the global namespace pollution has been a major issue causing countless production bugs which can be avoided with the use of JS modules or IFFEs.
The callback hell can be avoided with the use of asynchronous programming.
As people get more experienced with JS they become more accepting of it's quirks and manage to avoid it's pitfalls while being able to produce robust production ready code.

I think part of it is lingering feelings from way, way back when when every browser had their own implementations of certain features which meant that building any sort of platform that was going to work cross-browser was a major headache.
I remember adopting MooTools because it offered cross-browser AJAX support, then obviously jQuery when it came along with it's own solutions. These days most JS functions are normalised (ie. the fetch API) but there's a lot of salt in the wounds that can't be cleaned so easily.

I'm learning it just now, new job needs it. My biggest gripe is lack of typing of variables. I would like to know what kind of value, object, etc I can pass into a function.
Okay, I do like that they are called functions rather than methods. Cut my teeth on C and then Delphi (which had both functions and procedures) but it rankled me for the 10+ years I worked in Java that I had to say method.
Javascript does have something akin to function pointers, which is a nice throwback to C.
I’ve given up trying to be calm. However, I am open to feeling slightly less agitated.
I’m begging you for the benefit of everyone, don’t be STUPID.

Erm ... JS has both methods and functions - the former operate on object data (as per C#) the later are procedural and don't (as per C)
The difference in name is important because it tells you what you can do with a bit of code - that's why Java insists on method to differentiate it from the more primitive function you were used to in C.

Like I said, learning. Haven't gotten to that stuff yet.

One thing I disliked about Pascal is that it has Function and Procedure distinguished by keyword -- I prefer that C and its ilk don't, and have no keywords for those concepts.
I can understand why SQL does things more differentlier, and that's OK.

JavaScript is fine - I used in in various incarnations and Typescript definitely helps write cleaner code.
I heard Bob Martin point out that the evolution of programming languages is an evolution in constraining what you can do, each programming language constraining you in a different manner.
JavaScript is perhaps a bit of a exception in that it's fairly loose with its constraints which is why something like TypeScript makes sense as it brings static typing with it.
I still get caught out occasionally with the asynchronous nature of JavaScript but other than that I think it's fine when used well.

Javascript is great!..but I've been using it for 24+ years, so I'm used to it. Combined with CSS and AJAX, and there's not a lot you can't do.
My gripe is that after all this time, it's still a PITA to debug in Visual Studio. (probly cause I use master pages)
I still rely on the tried and true alert(whatami); debugging method.

I still use alert boxes for testing in JavaScript as well! I've been writing Javascript since about 1996 or so. In the beginning, there was no logging console available, so you really had to use alert boxes to test your code.
I love writing JavaScript. It's become so versatile over time that your imagination is the limit. It does have its strange quirks, but they present no problems if you know how to work with them. Why is it that in JavaScript, null is an object? In terms of conditional statements, that's when it gets really weird. If you compare null to undefined, the condition returns true. When you compare undefined to null, the condition returns false. If I remember correctly, that's how it goes, but I learned this so long ago that my memory is faint and vague. It's something along those lines, but either way, it goes to show how ridiculous JavaScript can be. Either way, I really like it!

I like JavaScript because it is so forgiving.
Error messages like NaN, undefined, are much gentler compared to a bunch of Error messages which come in C# projects on Visual Studio.
